Answer:
The first heart sound (S1) represents closure of the atrioventricular (mitral and tricuspid) valves as the ventricular pressures exceed atrial pressures at the beginning of systole (point a). S1 is normally a single sound because mitral and tricuspid valve closure occurs almost simultaneously.

Explanation:
Cells grouped together according to their similarity in shape, size, structure, intercellular materials, and functions are called tissues.
The growing of a cultivated crop (as corn) in strips alternating with strips of a sod-forming crop (as hay) arranged to follow an approximate contour of the land and minimize erosion.
Strip cropping helps to stop soil erosion by creating natural dams for water, helping to preserve the strength of the soil. Certain layers of plants will absorb minerals and water from the soil more effectively than others. When water reaches the weaker soil that lacks the minerals needed to make it stronger, it normally washes it away. When strips of soil are strong enough to slow down water from moving through them, the weaker soil can't wash away like it normally would. Because of this, farmland stays fertile much longer.
The term strip cropping also refers to a method of dry farming sometimes used in areas including parts of the Great Plains of the United States and the Prairies of Canada. To accumulate moisture in these dry areas, cropland is periodically left fallow. Typically, the fallow and planted areas are organized in parallel long, narrow strips that are oriented normal to the prevailing winds, in order to minimize the erosion of soil from the bare fields. Strip farming helps to prevent mass erosion by having the roots of crops hold on to the soil to prevent it from being washed away.
Hope this helps Its because its really strong soil
I think it would be: weathering, Deposition
Weathering and erosion
are very similar
